My invention relates to an efficient means for filling fountain pens`whereby the objectionable, and often obno`Xious,'covering of thefinger-grip end of the shell with ink 'isI avoided, and also Vwherebyink may be drawn and the pen'may be charged with the ink fromacontain'er, when the level of the ink is very low in the container.

In the preferred form of the invention, the

0 fountain pen is provided with an elastic bag whose outer end, ythatis, the end remote from tliepen end o f the fountain pen, may be openedand, upon expansion of the bag, the pen may be illed through the saidend. A suitable cap or plug or cover is provided for covering t-he outerend of the bag, whereby all exposed ink-smeared surfaces are entirelyenclosed while the penis in use.

The invention consists in other features and advantages which willappear from the following description and upon examination of thedrawing. Fountain pensV containing the invention may partake ofdifferent forms and may be varied in their details and still embody theinvention. To illustrate a pracf tical application of the invention, Ihave selected a fountain pen embodying ,the invention as an example ofthe various pens, and details thereof,that contain the invention andshall describe lthe selected pen hereinafter, it being understood'thatvariations may be made and that certain features of my invention may beused to advantange without the corresponding use of the other features,without departing from the spirit of the invention. The particularpenselected is shown in the accompanying drawing;

Fig. 1 illustrates al view of a longitudinal section of the fountain penreferred to. Fig. 40 2 illustrates a side view of the pen, a part of thepen being shown as broken away.

In the particular form of yfountain penl shown in the drawing, thefountain pen is provided with the Vusual shell v1', having the 4o penpoint holding member 2, andthe plug 3 andl an elastic ink bag ll, orother ink con# f tainer, that is connected to the member 2 and locatedwithin theshell 1. The pen point 5 1s fitted or vsecured in' the member2 and'is covered and enclosed by a-cap havingthe breather holes 7. krThepen-point 5 forms a" surface of a passageway that communicates with theinterior of the bag 4 throughfwhich' ink may be drawn into the bag 4andmay be allowed to be gradually' fed to the pen point 5, in the mannerwell known inthe art. Y The movement ofthe ink into theibag 4, in f thefilling operation, is brought about' by the usual bag depressing means,such as by means of a bar or plate 10 that, when depressed,`will forcethe air from within the resilient bag, and, when released, will permitthe bag t to expand anddraw ink into the bag, in the manner well knownin the art. The bar 10 may be depressed by a suitable means, such as thelever 11, that extends.throughv and lies l within the wall of the.shellv `and mayl be operated by the linger in the well known Infthe useof theordinary fountainy pen',` they pen point must be placed well belowY the level of the inkf in order to draw ,a ma'- p terial amount, of inkinto' thebarg.' Conse- "Q quently,fit is necessary thatthe'ink, inthef,`

` container from which itis to bewithdrawn,

has considerable depth. Itis often found troublesome to maintain the inkin the supply container sufliciently'full ofink, in order to properlylill the pen. In order to 'com-V pletely fill thepen, by the elasticityof the sci bag, after it has been forcibly collapsed by the bar 10, theend ofthe shell must be inserted within the ink to'prevent the entranceof the air between the plug 3 and the pen `point 5 into the passagewaysofthe plug 3 and the member 2,` and into the bag 4. This requires thatthe container shall have a-depth equal to the lengththat the penpoint 5pro` trudes'from ythe member 2 and invariably results in not only inkcovering'the entirey Y shown in the drawing is provided with a surfaceof the pen, and the plug 3, but also end of the fountain pen with inkand toV enable iilling of the pen from containers having ink at a lowlevel, I` have'. provided;

a means for filling the pen through the end of theshell remote from thepen point and enclosing and covering theexposed parts ofi the said meanswith a. suitable cap. The pen nipple 15. thatmay be secured'vin the endvof the shell 1A by any suitable means. UIn order. to easily assemblethebag 4 andthe member 2 Within the shell 1, the nipple 15 is so formed.that it may be moved into. the. con-` tracted end portion 16 of theshell 1 andsecured vby a suitable elastic ring 17 that, is located-1 ina channel:18 formedin the nipple 15., This willA prevent movement of the'nipple .15 inwardly into the shell 1. The nipple 15, hasa passageway 19that communicates with the interior of the bag, and theouterA endoftheb'ag and nipple is closed" by means of a, cap 20 that may bethreaded ontothereducedendportion 16 ofthe shell l. Preferably thebottom ofV thek cap 2O is provided with an elastic'disc 21 thatwillinsure sealing ofthe. end of the` nipple and.

closure ofthe end of the bagv4. The cap 20.'. may bereadily removed fromthe, shellA to open the bag. y

Asis vwell known, in connection with fountain pens, the passagewaysbetween the, penV point and the bag4 are frequently clogged bythickening of the ink and, consequently,

nkmay bedrawninto the bag 4 after the air is forced therefrom by the.operation of the bar 10 "through, thenipple 15. I Thenipple 15 maybeinserted into acontainer. and' the open endoffthe nipplemaylne-placed, if

desired, on thevbottom.ofthecontainer and so as to remove substantiallyall ofthe ink from the container, provided it does notex.-

ceed the capacity of, the bag 4. Further.-V

morethe cap` 6 alsoprevents the movement of a: material amount of, air4into the bag, since it coversthe pen.

25. The valve 25 may be a ball check valve, spring pressed by meansy ofthe spring- 26, located intermediate the ball-25 and the pin 27. Theball, 25 islocatedlin the recess28 which forms` a part ofthe passagewaythatinter- If. desired, the pen` pointend'of the bag 4 may be closed bymeansof asuitable valve.

connects the'pen point 5, and the bag 4, and is located in the penholder member 2. The

pen holder member is provided with a seat 29 that coacts with the ball25 to close the passageway 30 and, consequently, to close the pen pointend of the bag 4. In order to open the valve 25 and enable the flow ofthe ink from the bag to the pen point, and also to enable closure of thepen point end of the bag 4, when it is desired to draw ink into the bag4 through the nipple 15, a wire, or rod, 32 is located within the bagso, as to extend through the passageway' 30y of the pen point holdermember 2, and the passageway 19 of the nipple 15'. The length of thewire, or rod, 32, is such that,` when the'cap20 is screwed into the endof the shell 1, and the wire 32 is forced inward so that'it's end liesWithin the end of the nipple 15, the ball 25 will be raised from itsseat 29, substantially as shown in Fig. 1. Preferably, the` wire, orrod,.32, is bent at portions 33 located in proximity to the inner endsof the pen holder member, 2 andy of the nipple 15. This displacesthe.central'portion ofthe wire, or rod, 32 and also prevents the wire lfromdropping through the nipple 15 and. out ofv the passageway 30. This alsoenables the movement of the bar4 10 across ythe shell to the oppositeside ofthe shell duringy the compression of thebag4... Thus the pen maybe filled with'ink through either lend of the shell,

but, preferably, through the end remotefrom the ingergrip ofthepen,.that is, through the nipple 15 whichmay be closed ,by the lcap 20to cover any inlr smeared surfaces.
